Current condition
List bottle formats, neck details and complete closures using current drawings and samples. Record the presentation to filling and closing and the checks used to confirm each format.

Prepare the complete essential-oil bottle and closure range: drawings, neck details, inserts or droppers, filling access, seating and cleaning or format-change checks.
Provide the actual bottle and complete closure assembly for every required format, with current drawings and target fill quantities. Include inserts or droppers where used. Trial bottle presentation, access for filling, clean cut-off and closure seating with the actual oil, then agree what changes in adjustment, cleaning and finished-bottle checks between formats.
Use the supplier comparison guide and oil and pack checklist. Similar bottle volume does not establish the same filling access or closure requirements; retain the results for the formats actually trialled.
Plan essential oil bottling around your product, pack range, target output, cleaning needs and finished-pack checks. Discuss a practical line concept with Lancing using representative samples. Use this guide to resolve bottle and complete closure range before it limits the final system.
Discuss your application

List bottle formats, neck details and complete closures using current drawings and samples. Record the presentation to filling and closing and the checks used to confirm each format.
Include the smallest and largest bottle formats in your brief, along with each closure, insert or dropper where used. Ask which changes need a trial rather than assuming one setup covers the range.
Map how each bottle, neck or complete-closure change affects product presentation, filling access, closing, handling and included label position. Record what must be adjusted, cleaned and checked before accepting bottles from the next run.
Identify each essential oil and share product data and the conditions at filling. Ask how product-contact materials and cleaning suitability will be reviewed, then trial the actual oil rather than assuming every product behaves the same.
Send bottle drawings and samples with the complete closure assembly, including inserts or droppers where used. Review bottle presentation, access for filling and closure seating across the formats you need.
State the fill quantities and agree how they will be checked with the supplier. Include the range of bottles and a record of acceptable results; a nominal fill alone does not define the acceptance trial.
Describe batch sizes, production pattern and required output, including replenishment and stops. Ask what the complete filling and closing sequence must demonstrate; no equipment rate is assumed.
List the oil, bottle and closure changes, cleaning needs and operator access. Agree what must be cleaned, adjusted and checked before the first accepted bottle of the next run.
Agree checks for fill quantity, clean cut-off, closure seating and label position where included. State how unsuitable bottles are identified, handled and recorded before accepting the trial.
